IBM laid off 1,315 US workers from its global services division, a union group under the Communications Workers of America has said.
An IBM spokesperson could not immediately be reached for confirmation.
The company said at an investors' conference last month that it would reduce costs in the US and noted a slowdown in its domestic enterprise business. IBM reported its net profit rose 8% year-over-year in the first quarter to $1.8 billion (£900 million).
The layoffs come just a day after IBM announced plans to open a new call centre in Indiana that will eventually create 500 jobs. The call centre investment was reportedly made in return for a 10-year, $1.16 billion contract with the state’s Family and Social Services Administration.
